TROLLEY-WHEEL AND MOUNTING THEREFOR.

Specification of Letters Patent.

Patented NOV. 21, 1905.

Application filed April 15, 1905. Serial No. 255,804-

lb all whom it may concern.-

Be it known that I, FRANK N. RUssnLL, a resident of Elmira, in thecounty of Ohemung and State of New York, have invented certain new anduseful Improvements in Trolley- Wheels and Mountings Therefor; and I dohereby declare the following to be a full,clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to improvements in trolley-Wheels and mountingstherefor, the object of the invention being to provide improvements ofthis character in which the trolley-wheel is so mounted as to permit itslateral tilting to accommodate itself to varying positions of thetrolley-wire, particularlywhile rounding a curve; and the inventionconsists in certain novel features of construction and combinations andarrangements of parts, as will be more fully hereinafter described, andpointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective Viewillustrating my improvements. Fig. 2 is a View in longitudinalcrosssection, and Figs. 3 and 4 are views of details of construction.

1 represents a trolley-pole provided at one end with my improved harp 2,having general fork formation, made with wide fiat parallel side members3, as clearly shown. These flat side members 3 are provided with alinedscrew-threaded openings to receive bearing blocks or cups 4, screwedtherein. These cups 4 are made on their inner faces with sphericalsockets or hearings to receive the spherical journals or enlargements 5at the sides of my improved trolley-wheel 6. The trolley-wheel isprovided around its journals or enlargements 5 with annular shoulders?to engage the bearing blocks or cups 4: and limit the lateral tiltingmovement of the trolley-wheel, yet not interfere with the free rotarymovement thereof.

The trolley-wheel 6 is made hollow to form a lubricant-receptacle, intowhich the lubricant can be inserted through an inlet-port 8 at one side,and openings 9 are made in the trolley-journals to permit free passageof the lubricant to the bearings.

The bearing block or cup at one side is made with an angular socketformed by parallel lugs 10 to receive and hold the head of a bolt 11against turning, and said bolt passes through comparatively largeopenings in the walls of the trolley and is screwed into an opening inthe other bearing block or cup, and said latter cup, or both, ifdesired, is or are held against turning by means of a lockscrew 12,screwed into an opening formed by alined notches 13 let in the block orcup and harp. By providing several notches 14in the block the latter canbe secured at difierent adjustments, so as to cause the blocks toproperly hold the spherical hub of the particular wheel placed betweenthem with more or less pressure, as may be desired.

A great many changes might be made in the general form and arrangementof the parts described without departing from my invention, and hence Iwould have it understood that I do not restrict myself to the precisedetails set forth, but consider myself at liberty to make such slightchanges and alterations as fairly fall within the spirit and scope of myinvention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with a fork, of bearing blocks or cups adjustable inthe fork and having sockets therein, and a trolley-wheel havingsemispherical journals or enlargements having fixed relation to eachother. and to the wheel and mounted in said bearing blocks or cups.

2. The combination with a fork, of bearing blocks or cups screwed intoopenings in the ing openings communicating with the lubricant-chamber.

4. The combination With a trolley-fork having threaded openings in itssides, of bearing blocks or cups screwed into saidv openings and havingsockets in their inner faces, a trolleywheel having semisphericaljournals located in the sockets, annular shoulders around said journalsto limit the tilting of the wheel, a bolt passed through the blocks andwheel, an angular socket on one block for the head of the bolt and athreaded opening in the other block for the threaded end of the bolt.

5. The combination with a fork having sockets in its arms, of atrolley-wheel having spherical enlargements to enter said sockets andhaving a large central opening, a bolt passing through said opening andthe arms of the fork for connecting theparts together and shoulders onthe wheel to engage the arms of the fork.

6. The combination with a fork having sockets therein, of atrolley-wheel having spherical enlargements to turn in said sockets, anda clamping-bolt passed through the fork and through a wide opening inthe wheel to hold the parts together.
